CIRCUIT-CLOSER FOR FIRE-ALARM SYSTEMS.

Specification of Letters Patent.

Patented Sept. 26, 1916.

IA'pplication filed June 18, 1915. Serial No. 84,911.

To all whom it may concerni- Be it known that I,' FERN R. BAILEY, a citizen of the United States, residing at Manzanola, in the county of Otero and State of Colorado, have invented new and useful Improvements in Circuit-Closers for Fire- Alarm Systems, of which the following is a specification.

This invention relates to improvements in fire alarm systems and has particular application to an electric fire alarm system.

In carrying out the present invention, it is my purpose to provide a fire alarm system which will embody in its construction, among other features, circuit closers and cords holding the circuit closers normally in position and adapted to release the same when burned so that the alarm circuit controlled by the circuit closers will be. closed, the cords forming connections between the circuit closers.

It is also my purpose to provide a fire alarm system wherein by means of charges of powder associated with the respective circuit closers, and fuses leading to such charges of powder and disposed along the -walls and beneath the floors of a building,

the circuit closers may be actuated to closed position by the explosion of the charges of powder upon the igniting of the fuses.

With the above and other objects in view, the invention consists in the construction, combination and arrangement of parts hereinafter set forth in and falling within the scope of the claim.

In the accompanying drawing; Figure 1 is a view in side elevation of one of the (Sircuit closers employed in my system. Fig. 2 is a longitudinal sectional. view therethrough. Fig. 3 is a cross sectional view through the same. Fig. 4 is a diagrammatic plan view of the system.

Referring now to the drawing in detail,

each circuit closer is indicated as an entirety by the numeral 1 and comprises a substantially rectangular casing 2 constructed of metal or other suitable material and having the end walls thereof formed with pairs of alining openings 3, 3, 4, 4 and 5, 5. Suitably secured within the casing 2 adjacent to each end thereof are tubular containers 6 and 7 and the containers 6, 6 aline with the respective openings 3, 3, while the containers 7, 7 are coaxial with the openings 5, 5 respectively. Disposed in axial alinement with' the openings 4, 4 respectively and suitably fastened within the casmg are tubular containers 8, 8. Disposed within the confronting ends of the respective containers 6, 6 are plugs 9, 9, while arranged within the similar ends of the containers 7, 7 are plugs 10 respectively and I tainers 6, 7 and 8 at one end of the casing 2 are insulated therefrom and from each other and are electrically connected by way of a wire 14 with a binding post 15 secured to the outer surface of the casing and insulated therefrom and connected to the casing adjacent to the binding post 15 and in contact with such casing is a second binding post 16.- The binding posts 15 and 16 of each circuit closer are connected across the legs of an alarm circuit 17 including a suitable source of electrical energy as a battery 18 and an alarm 19 preferably in the form of a bell. The outer ends of the plungers 12 of the respective circuit closers are connected ,in series with each other by means of cords 20. Secured within the respective containers 6 are the ends of fuses 21 extending along the walls and under the floors of the protected structure.

In practice, should any one of the fuses 21 become "ignited, such fuse-will burn and explode the powder charge in the particular receptacle, thereby forcing the plug 9 in such receptacle into engagement wlth the companion plug 9 with the effect to close the circuit 17 and so sound the alarm 19. Should one or more of the cords 2O become ignited and part the springs 13, upon being relieved of the influence of such cords, will react and slide the plungers 12 into engagement with each other, thereby bridging the circuit 17 and sounding the alarm.-

While I have herein shown and described one preferred form of my invention by Way of illustration, I wish it to be understood that I do not limit or confine myself to the precise details of construction, herein doscribed and delineated, as modification and variation may be made within the scope of the claim without departing from the spirit of the invention.

I claim:

A circuit closer comprising asubstantially rectangular casing having the end walls thereof formed with alining openings, containers secured to the respective end walls of said casing concentrically of the openings therein, plugs in the confronting ends of said containers, powder charges in said containers behind the respective plugs, cir- 'euit connections for said containers, and

fuses extending through the openings in the end Walls of said casing and embedded in said powder charges and adapted when ignited to explode the powder charges whereby said plugs will be moved into engagement with each other to close the controlled circuit.

In testimony whereof I afiix my signature in presence of two witnesses.
